CT images with body weight loading are desired for preoperative planning on
TKA surgery. In our proposed method, we perform stress analysis by the finite
element method (FEM) for bone mesh structure by generating CT images, and
we estimate an ideal standing position of the loaded state (referred to as
deformed CT images of the ideal standing position). We also compare the
deformed CT image with CR images, and evaluate the effectiveness in several
ways.
